CUT-OUT PLUG.

` Specification of Letters Patent.

Patented ct. 26, 153120.

Application led ctober 15, 1919. Serial No. 330,859.

lowing is a specification.

The invention relates to improvements in cut-out plugs, as described inthe present specification and shown in the accompanying drawings that.form a part of saine.

The invention consists essentially ofthe novel features 'of constructionwhereby the electric circuit may be broken Within the Tghe objects ofthe invention are to provide a means for breaking the electric circuitother than by disengaging one or other of the terminal plugs, to providea device especially adapted foruse in connection with electric irons,toasters and other like devices, to reduce to a minimum the strain on,the electric wiring, and generally to provide a cut-out plug which willbe inexpensive to construct, simple and safe to operate durable andeflicient. I l In the drawings Figure 1 is a. plan view of a plug withone side thereof4 removed,

Fig. 2 is a longitudinal sectional view through the casing taken on theline A-A of Fig. 1, the sliding conductor-being shown in full.

Fig. 3 is a plan view of the device assembled.

Lilie numerals of reference indicate cor responding parts in the variousfigures.

Referring to the drawings 1 and 2 are the two halves of thecasingcomposed. of

`fiber, rubber or other non-conductive material such as is usual in theconstruction of devices of this nature, said halves or sections beingadapted to be secured together by bolts 3 and nuts et as customary.

5 are contact terminals adapted to receive the pins or other forni ofprojections :from

the device to which .the current is to be supplied, said contactterminals being contained in parallel longitudinal slots 6 .extendinginwardly from 'the ends of the sections 1 and 2.

7 are substantially U shaped-spring clips secured to the inner endsrespectively of the contact terminals 5 and projecting inwardlytherefrom in the slots I., the ends of said the jumpers.

ifs'ual guard composed of coiled' clips preferably being turnedoutwardly t'o form guides for the jumpers.

8 are terminal lugs located at the opposite end of the casing from theterminals 5 and to which the wires 9 are adapted to be secured.-

10 are spring clips secured to the lugs 8 Vrespectively and projectinginwardly therefrom' a. 'short distance in slots 1l, said clips' 10 beingconsiderably shorter than the clips 7 12 are jumpers composed of metalstrips' slidable longitudinally of the casing iii slots in the sections1 and 2, said jumpers being of such a length that when drawn to theextreme inner ends of the clips 7 the other ends thereof will terminateconsiderably short of the ends ofthe clips 10 tliiis'breaking the'connection between said clips 7 and l() but when drawn iiito the clips10 the other ends will still. engage the clips 7 and thus forni a ineensof completing the electric circuit between the opposing terminals.

13 is an elongated block composed ofnon conductive material and slidingin a longitudinal slot 14 located between the jumpers 12, said blockbeing connected to said jump ers and being for the purpose of providingameans for moving the two jumpers in unison.

AThe jumpers are shown. in the drawings as being provided with opposingo'lfsets 1F secured to opposite sides of the block 18 and sliding insuitable grooves in the casing but it is apparent that said jumpers andsaid block may be secured together in various waysl such as by providingthe block with right angle extensions which may besecuredl to said.jumpers.

The block 13 is provided with a lug 16 through a slot 1T in one of thesections of the casing to provide a means for operating 18 is the wirehaving a reinforced end 19 adapted to 'be inserted in a slot inthecasing.

ln the operation of this invention the pl iig is connected to the ironor other de vice iii the usual Way, that is to say the projections fromsaid device are inserted in the clips or contact terminals 5, andthelugA 16 is then drawn to the extreme head. end of the slot 17 in thecasing ,which has the effeet ofdrawiii,i` the jumpers into elngage- A 2Lessen ment with the clips 10 'and competing the y circuit between theterminals 5 and 8l Vhen the device is sufficiently hot or when for anyother reason it;v is desired te shut ofi' the current for en indeinitetime it. is simply necessery'to .push he ug 16 to i the opposite end ofthe slot l? which frees the jumpers from engagement 'with the cips 10and. breaks the circuitu This device will be found of decided edAVantage in eases Where it is not convenient to turn off the current etthe usuel switch,

such as when the device is being u sedin con nection with a toasterwhich is usually 1ocated on the dining table wherees the usuel switch isfrequently n considerable distance away.

Vhat I claim is:

In a cui; out plug, e casing, divided eentraly and ormingsectons adaptedte be detaehebly secured together, Contact terminals purellelly eirangedin sots extend.w

ing inwardly from one end of seid casing,

spring dips secured e the inne ends e?? seid berminels and prejeeingimveiody eerminel lugs located in slots from the ether end of saidcasing, spring clips secured te @he in* nel ends of seid lugs andvprejeeing inwardly and terminating shert ef the first mentioned eiipsand being shorter einen said rst mentioned clips, jumpers in continuousengagement with the clips from said conmet terminals end slideble inseid easing to engage the clips fom said terminal lugs, e.non-conductive block slideble in said cesing between said jumpers andsecured toesets from said jumpers and e lng from said block extendingthrough one seeiee of seid casing and opemting in a sieb therein Signedat the city of Toronto his th dey of October i919.
